This study, conducted by Ms. Dipika Thakur and Ms. Shahina Shaikh at Adani Vidya Mandir Ahmedabad, integrates tessellation art into Class 9 quadrilateral theorem teaching to enhance conceptual understanding beyond rote-learning limitations. Employing a five-phase design—traditional teaching, pre-assessment, art-integrated teaching (tessellation art and load-bearing paper folding), post-assessment, and comparative analysis—the research evaluates art-based methods' impact on engagement and comprehension. Pre-tests revealed significant gaps in students' grasp of quadrilateral properties. The art-integrated phase used hands-on tessellation activities to visualise abstract concepts tangibly, boosting participation and enthusiasm. Post-tests, mirroring pre-test formats, showed marked improvements—e.g., students scoring 0.5-1 initially reached 9.5-10. Graphical comparisons and qualitative feedback from teachers/students highlighted trends in better understanding, accessibility, and enjoyment. In conclusion, tessellation art fosters deeper engagement and conceptual mastery, offering a transformative alternative to traditional geometry instruction with broader STEM education implications.
